TriNessa® is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. TriNessa is indicated for the treatment of moderate acne vulgaris in females at least 15 years of age, who have no known contraindications to oral contraceptive therapy, and have achieved menarche. TriNessa should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control. Oral contraceptives are highly effective for pregnancy prevention. Table II lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the Norplant System depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. TriNessa has not been studied for and is not indicated for use in emergency contraception. In four clinical trials with TriNessa, a total of 4,756 subjects completed 45,244 cycles, and the use-efficacy pregnancy rate was approximately 1 pregnancy per 100 womenyears. TriNessa was evaluated for the treatment of acne vulgaris in two randomized, double-blind, placebo-controlled, multicenter, Phase 3, six (28 day) cycle studies.221 patients received TriNessa and 234 patients received placebo. Mean age at enrollment for both groups was 28 years. At the end of 6 months, the mean total lesion count changes from 55 to 31 (42% reduction) in patients treated with TriNessa and from 54 to 38 (27% reduction) in patients similarly treated with placebo.Table III summarizes the changes in lesion count for each type of lesion in the ITT population. Based on the investigator’s global assessment conducted at the final visit, patients treated with TriNessa showed a statistically significant improvement in total lesions compared to those treated with placebo.
